Flashing member and frame for a roof-penetrating building part

ABSTRACT

A flashing frame for a roof-penetrating building part, in particular in a roof window frame, comprises mutually connected frame members ( 6, 12 ) of weather-shielding material for positioning along the sides ( 1-4 ) of the roof-penetrating building part adjoining the roofing. The frame members for positioning along sides ( 3, 4 ) of the roof-penetrating building member, which do not extend perpendicularly to the pitch of the roof, consist of flashing members ( 7 ) designed as L-profiles with a profile wall ( 8 ) for positioning at least partially under the roofing ( 5 ), and an upright profile wall ( 9 ) for positioning in abutment against the side of the roof-penetrating building part. Flashing members ( 7 ) are placed in the side frame members in extension of each other with mutual overlapping. The upright profile wall ( 9 ) is provided with a comparatively closely packed, substantially equidistant, transverse profiling ( 10 ) and with locking means ( 11 ) for mutaul locking of the mutually overlapping parts of the neighbouring flashing members ( 7 ).

BACKGROUND OF THE INVENTION

The present invention relates to a flashing member for a flashing framefor weather-shielding connection of a roof-penetrating building part toan adjacent roofing, said member comprising an L-profile with a firstprofile wall for positioning at least partially under the roofing and asecond, upright profile wall for positioning along a side of theroof-penetrating building part facing the roofing.

Flashing frames composed partly of mutually overlapping flashing membersof this type are known for instance from U.S. Pat. No. 4,951,431 andSE-B-416072 for flashing of roof-penetrating building parts likechimneys, walls, etc.

The invention aims in particular at providing an improved flashing frameof the type in question for weather-shielding mounting of the framestructure of a roof window in a pitched roof, in particular one withflat roofing, for instance slates, but may also be adapted to othertypes of roof-penetrating building parts like for instance chimneys, airshafts and the like.

When mounting roof windows in such pitched roofs, it is i.a. known fromDE-B-21 42 733 to use mutually overlapping frame members in the form ofL-profiles in abutment against the sides of the window frame in parallelwith the pitch of the roof. In this known design, the upright profilewall of the L-profiles has a comparatively low height, such that for itsweather-shielding connection with a superjacent covering member on theframe side, a separate insert profile with hook-and/or bead-shapedengagement means is needed for sealing connection with the uprightprofile wall of the L-profile and the superjacent frame covering member,respectively.

Though it is thereby possible to avoid the otherwise necessary securingof the upright wall of the L-profile to the frame side member, whichmostly consists of wood, by means of screws or nails which are driventhrough the upright profile wall and which may give rise to a subsequentrisk of water-penetration into the frame side member and possibly theroof structure itself, the construction becomes complicated and moreexpensive and the mounting is made difficult on account of the special,separate insertion profile.

BRIEF SUMMARY OF THE INVENTION

On this background, it is the object of the invention to provide aflashing member which is designed in such a manner that severalindividual members in a simple manner may be connected in partlyoverlapping relationship in extension of one another under mutualinterlocking of overlapping members to prevent relative displacementthereof for the formation of a continuous frame member, and which is atthe same time simple in manufacture and easy to handle and mount on thebuilding site without the use of screws, nails or the like fasteningmembers for securing to the roof-penetrating building part.

To meet this object the flashing member according to the invention ischaracterized in that the upright profile wall is provided with aprofiling for engaging a corresponding profiling in the upright profilewall of an overlapping, longitudinally displaced neighbouring member inthe flashing frame for preventing longitudinal displacement between saidmembers and provided with integral locking means for locking the memberrelative to said neighbouring member, said locking means comprising aprotruding, locking flap at at least one end of the member, said lockingflap being bendable to a locking position by manual deformation.

In a preferred embodiment of the flashing member, the profile may bemanufactured by punching of sheet flashing material, for instancealuminium sheet material, followed by profiling of the upright profilewall, which may advantageously consist of a pleating or corrugation withcomparatively closely packed foldings or waves as know per se fromGB-A-2189275. On the installation site, the L-profiles are easily andquickly connected in extension of each other under mutual overlapping,and the overlapping parts of the two neighbouring members are mutuallyinterlocked by means of the manually bendable locking flaps.

Advantageous embodiments of such a flashing member are stated herein.

Moreover, the invention relates to a flashing frame forweather-shielding connection of a roof-penetrating building part to anadjacent roofing, in particular in a pitched roof, which frame comprisesmutually connected frame members of weather-shielding material forpositioning along the sides of the roof-penetrating building part, saidsides facing the roofing, whereby frame members for positioning alongsides of the roof-penetrating building member which do not extendperpendicularly to the pitch of the roof consist of flashing memberspositioned in extension of each other with mutual overlapping asexplained above.

According to the invention such a flashing frame is characterized inthat for positioning against sides of the roof-penetrating buildingpart, which extend perpendicularly to the pitch of the roof, theflashing frame comprises throughgoing frame members for abutment againstsaid sides in their entire extension, a frame member for positioningagainst an upperside of the roof-penetrating building part beingdesigned as a hood-like member for overlapping the upper flashing memberin each adjacent side frame member.

In addition to the advantages described above, this design of the sideframe members makes a sealing connection possible of the throughgoingframe members for positioning against the sides of the roof-penetratingbuilding part which are perpendicular to the pitch of the roof, forinstance top and bottom members of the frame for a roof window.

The invention will now be explained in the following with reference tothe schematic drawing, in which

FIG. 1 is a perspective view of an embodiment of a flashing framecomprising side frame members consisting of flashing members accordingto the invention,

FIG. 2 an embodiment of a flashing member according to the invention,and

FIG. 3 example of a side frame member consisting of flashing members asshown in FIG. 2 mounted along one side of a roof-penetrating buildingpart in the form of a chimney in connection with a roof covering ofslates.

DETAILED DESCRIPTION OF THE INVENTION

In the embodiment shown in FIG. 1 of a flashing frame forweather-shielding connection of the frame structure of a roof window,said frame structure consisting of top and bottom members 1 and 2 andside members 3 and 4 for a roofing consisting of slates 5, the flashingframe comprises a throughgoing bottom member 6 to be positioned againstthe frame bottom member 2 in its entire extension and secured thereto,for instance by means of screws.

For mounting against the frame side members 3 and 4, the flashing framecomprises side frame members composed of flashing members 7 in the formof L-profiles which, as more clearly shown in FIG. 2, comprise a profilewall 8 in parallel with the roof and which at least partially may beinserted under the slate 5, and an upright profile wall 9 provided witha transverse profiling, for instance as shown in the form of a pleatingwith comparatively, closely packed, equi-distant foldings 10.

According to the invention, the upright profile walls 9 are further atleast at one end provided with locking means, preferably in the form ofa protruding locking flap 11, which after the positioning of the members7 in extension of one another under mutual overlapping may be manuallybent over for locking of the overlapping parts of neighbouring members7.

The locking flap 11, which in the not bent position shown in FIG. 2,protrudes from the upright profile wall 9 in plane therewith, isprovided with the same profiling as the upright wall 9 and with a width,which comprises for instance two to six of the foldings 10 of thepleating. In this manner an effective locking of the overlapping partsof the flashing members is obtained, such that the side frame memberscomposed of the members are kept in close abutment against the frameside members 3 and 4 without being secured thereto by means of screws,nails or the like.

After mounting of the members 7 in extension of one another against theframe side members 3 and 4, the flashing frame is finished by athroughgoing top member 12 which, as shown, may have a hood-like shapefor partial overlapping of the upper flashing members 7 in each sideframe member.

As shown in FIG. 2, the profile wall 8 of the flashing member 7 intendedfor being positioned under the roofing may preferably be provided withcorner recesses 16 of the same size and shape as the locking flaps 11,such that the flashing members 7 may be manufactured from a sheetmaterial without any waste of material.

In the embodiment shown in FIG. 2, the flashing member 7 is providedwith two locking flaps 11 and corresponding thereto, the profile wall 8is provided with two corner recesses 16. In this way the same design ofthe flashing member 7 may be used on all sides of a roof-penetratingbuilding part which are not perpendicular to the pitch of the roof, anda correct overlapping in respect of water drainage is obtained betweenneighbouring members as will be seen from FIG. 3, which shows theoverlapping between two neighbouring members 7 with locking flaps 11 aand 11 b in bent locking position for providing a side frame member formounting against one side of a roof-penetrating building part in theform of a chimney 17.

Furthermore, a longitudinal groove 14 may optionally be provided in theprofile wall 8, in which groove a sealing member for sealing against theunderside of the roofing may be placed, and the profile wall 8 mayfurther have pre-made nailholes 15 for use in securing the flashingmembers to battens in the subjacent roof structure.
